To markup a screenshot immediately after taking it, press Side button + Volume Up, tap the thumbnail, and use the editing tools like pen, text, shapes, or eraser, then save or share. 2. For photos already in your camera roll, open the Photos app, select the image, tap Edit, then the markup icon to annotate with the same tools, and save as a new copy by default. 3. After markup, tap Done and Share to send via Messages, Mail, Notes, or other apps, or use markup directly in Notes by inserting a photo and selecting markup. 4. Use hidden tips like two-finger press for a ruler to draw straight lines, pinch to resize text, let iOS auto-clean shapes, and shake to undo if enabled. The built-in markup tool is efficient for basic annotations, eliminating the need for third-party apps, allowing you to quickly edit, annotate, and share directly from your iPhone.

You can easily mark up screenshots and photos directly on your iPhone using built-in editing tools. Whether you’re highlighting something, adding text, or drawing attention with arrows, here’s how to do it quickly and effectively.

1. Markup a Screenshot Right After Taking It

The fastest way to markup a screenshot is immediately after you take it:

• Take a screenshot by pressing the Side button + Volume Up button (on newer iPhones).
• A thumbnail of the screenshot will appear in the lower-left corner of the screen.
• Tap the thumbnail to open the markup editor.
• Use the tools at the bottom:
  • Pen, pencil, crayon, or highlighter – draw freehand.
  • Marker – for bolder lines.
  • Eraser – remove marks.
  • Lasso tool – select and move a drawn element.
  • Add text – tap the "+" icon and choose “Text” to type.
  • Shapes – add perfect circles, squares, arrows, etc. (iOS automatically detects your drawing).
  • Magnifier – create a zoomed-in inset.
  • Color palette – change the color of your tools.
• When done, tap Done, then Save to Photos or share directly.

Pro tip: If you miss the thumbnail, don’t worry — you can still edit it later from the Photos app.

2. Edit Photos or Screenshots Already in Your Camera Roll

You can markup any photo or screenshot saved in your library:

• Open the Photos app.
• Select the photo or screenshot you want to edit.
• Tap Edit in the top-right corner.
• Tap the Markup icon (it looks like a pen tip in a circle, usually at the bottom).
• Use the same tools as above to draw, add text, insert shapes, etc.
• Tap Done when finished.

Note: This doesn’t replace the original unless you choose “Save as New Copy” or overwrite it. By default, iOS saves a new version.

3. Use Markup to Annotate and Share Quickly

Markup is great for quick communication:

• After marking up a screenshot, tap Done and then Share.
• Choose how to send it: Messages, Mail, Notes, or any app.
• You can also use markup in other apps like Notes:
  • In a note, tap the camera icon > Scan Documents or Take Photo, then tap the image and select Markup.

4. Hidden Tips for Better Markups

• Use the ruler for straight lines: Press and hold with two fingers to bring up a ruler. Draw along it for perfectly straight lines or arrows.
• Resize and move text boxes: After adding text, pinch to resize or drag to reposition.
• Auto-shape detection: Draw a rough circle or square, then lift your finger — iOS will clean it into a perfect shape.
• Undo easily: Shake your iPhone to bring up the undo prompt (if enabled in Settings > Accessibility > Touch > Shake to Undo).

Basically, the markup tool is powerful but simple — no need for third-party apps for basic annotations. Just tap, draw, and share.
